Alexis Jeffery seen on CCTV hours before body was found

A man captured on security footage with murdered woman Alexis Jeffery may be the last person to see her alive, hours before the 24-year-old's body was found on a riverbank at the Queensland/NSW border.

The footage from the Royal Hotel in Goondiwindi shows the man approach Ms Jeffery from behind. The pair then walk together along the town's main thoroughfare, Marshall Street at 2.16am on March 16.

The young mother's partially clothed body was discovered about nine hours later next to the Macintyre River, only a few hundred metres away from her home.

Investigators have declined to name the local man and said he has not been declared a suspect, only a person of interest. Police believe the man and Ms Jeffery were friends and not in a relationship.

A post-mortem is yet to be formally completed but police believe Ms Jeffery died from a physical attack.

"Police are still awaiting the final results of forensic examination...there was no physical signs of trauma with respect to a sexual assault," Acting Superintendent Isherwood said.

Ms Jeffery set out on the evening of March 15 and was at The Queensland Hotel, before making her way to The Royal Hotel.

A month on from Ms Jeffery's death, the acting inspector said the case had been difficult to crack.

"We think it was someone the victim knew. There's nothing to suggest at this time it was a random act," he said.

"I was in Goondiwindi this morning and there is some fear within the community with respect to what's occurred. If it was in a strip such as Brisbane where there is a lot of activity, there is the likelihood that someone would have seen something."
